Fixed orthography in sandman_de.ts

[NewKidOnTheBlock]

Two things to note:

1. I've deleted all instances of <oldsource>
2. @DavidXanatos At one point, you have to decide how SandboxiePlus is supposed to be spelled officially:
   a) Sandboxie Plus (~a handful of instances)
   b) SandboxiePlus (~a dozen instances)
   c) Sandboxie-Plus (~50 instances)

To establish congruity, I've converted all occurrences of a) & b) --> c) in this edit.

@DavidXanatos
What is the official spelling?
It keeps contradicting itself; very often on the same page.

This pull request has certainly aged badly, the direct edit of <source> strings in .ts files is to avoid completely, unless you also edit the respective source files.

See this note from the Localization notes:

⚠️ You shouldn't ever edit the text in the source tags of the .ts file if you don't apply the same edit on the respective source code file. For example, see the following commit: 3b86441.

See also my reply in the Slack channel:

Updating sandman_en.ts is not a feasible option, because that file is based on the source files (which are the only ones you should update as minimum).
Once those are updated, the lupdate workflow takes care of updating all the .ts files every night through a schedule.
However, the manual removal of <oldsource> references might be OK.

Understood. The .ts files are auto-generated and shouldn't be touched as they get their values from somewhere else.

This leaves the question what should be edited instead.
The main goal of my 2-hour editing session was to fix the word capitalisation in the Sandboxie Plus options.
I fine-combed through every single tab.

Just have look, this is a user's first impression of the SB Plus options:

The orthgraphy is alright, but tHe CaPitAlisAtION is all over the place, often contradicting itself.

Those entries are part of SettingsWindow.ui, however, when there are .ui files to fix in the middle, it would be highly recommended to report them directly to @DavidXanatos.

I remember a lot of typos in .ui files already fixed in pull requests but suddenly restored. Apparently there are some synchronisation issues with .ui files in the Qt environment from which David creates the builds.
